HOSE-CLAM P.

SPECIFICATION forming part of Letters Patent No. 483,302, datedSeptember 2'7, 1892.

Application filed January 6, 1892- Serial No. 417,178- (No model.)

To all whom it may concern:

Be it known that I, AUSTIN RAY DICKIN- SON, of Syracuse, in the countyof Onondaga, in the State of New York,have invented new and usefulImprovements in Hose-Clamps, of which the following, taken in connectionwith the accompanying drawings, is a full, clear, and exact description.

The object of this invention is to provide a hose-clamp which shall besimple and cheap in construction and at the same time possess greatstrength and efiiciency in its operation; and to that end the inventionconsists of a single band stamped out of sheet metal, perforated at eachend, and tongues extending from one or both ends, said band being bentin circular shape and its end portions bent radially outward and thetongues continued in an unbroken line of curvature with the band andpassing under the opposite end of the band, as hereinafter more fullydescribed, and specifically set forth in the claims.

Figures 1 and 2 are side views of my improved hose-clamp. Fig. 3 is anedge view of the same. Fig. 4 is a transverse section on line a: as,Fig. 3. Fig. 5 is a plan View of the blank from which the hose-clamp isformed, and Fig. 6 is a plan view of a blank embodying modifications ofmy invention.

Similar letters of reference indicate corresponding parts.

6 represents the band, which when applied to a hose is made to tightlyembrace the same by means of the bolt a, passing through the perforatedears 0 c and provided at one end with a head and on the opposite endwith a nut, by which to tighten the band, as aforesaid. By means oftongues 25 t, extending across the space between the ends of the bandand lapping onto the inner side of the band, the liability of the hosebecoming crimped or buckled up between the ends of the band is obviated.This band, with its aforesaid perforated ears and tongues,I form in onepiece stampedout of suitable sheet metal, as shown in Figs. 5 and 6 ofthe drawings. In the end portions 0 c of this blank are punched theperforations (Z (Z, preferably by the same die which stamps out theblank. Said die also makes the incision c e, and thereby forms thetonguestt. I preferably form said tongues on both ends of the blank, asshown in Fig. 5

of the drawings, and make said incisions from opposite edges of the bandand curvilinear, so as to cause the tongues to extend, respectively,from opposite sides of the end portions of the blank and beyond the sameand toward the opposite edges of the blank, as shown in said figure ofthe drawings.

In forming the hose-clamp from the described blankthe same is bent incircular shape and the perforated end portions 0 c are bent radiallyoutward and the tongues 25 t are continued in the same curvature withthe main portion of the blank and slipped under the opposite end of thecircular portion of the band, as shown in Fig. 3 of the drawings.

This construction obviates abrupt bends of the tongues, and thusstrengthens the same and reduces the cost of manufacture. The 70clamping-bolt a is inserted into the perforations cl (Z and a nutnapplied to the bolt and tightened to cause the band to firmly grasp thehose. I do not, however, limit myself to the use of the tongues or bothends of the band, inasmuch as said tongues may be formed only on one endof the band, as shown in Fig. 6 of the drawings. Said fingers are atopposite sides of the ears 0 c and may be united, as shown by full linesin said figure.

What I claim as my invention is-- 1. As an improved article ofmanufacture, a hose-clamp formed of a single band of sheet metalperforated at each end and tongues extending from one or both ends, saidband being bent circular shape and its perforatedend portions bentradially outward and the tongues continued in the same line of curvaturewith the band and extending under the opposite end of theband,substantially as described aud shown.

2. The within-described blank, consisting of the band I), having theperforated-end portions 0 c and the tongues 25 6, respectively, onopposite sides of said end portions and ex tending beyond the same andtoward the opposite edges of the band, substantially as described andshown.

In testimony whereof I have hereunto signed my name this 261 day ofJanuary, 1892.

AUSTIN RAY DICKINSON. [L. s]
